When it comes to power electronics at the module level, the world’s photovoltaic markets are divided. While it is very common for solar technology specialists in the U.S. to install power optimizers (MLPE) in PV systems to meet the relevant installation regulations, these devices are the subject of considerable controversy in the rest of the world. Sweden, for example, has even issued a partial ban on the sale and installation of power optimizers from one major manufacturer because they do not meet the applicable electromagnetic compatibility (EMC) requirements.* So what’s the story with MLPE? What is really technically relevant, and what is just clever marketing? We resolve five common myths about power optimizers.
The first 18 months of field experience with the charging solution SMA EV Charger have shown in Sunny Portal: more than half of the energy used for charging electric vehicles is provided by solar power from your own roof. It is no longer a secret that this allows you to be on the move in a particularly climate-neutral and cost-effective way. But did you know that it means you can even prevent expensive grid expansion and your contribution to the energy transition becomes even more valuable?
On March 3, 2022, a serious power outage in Taiwan, happened. More than five million households and 500 industrial businesses were affected. Thanks to the SMA storage solution, however, they were quickly back on the grid and supplied with power. The example clearly shows the importance of storage solutions in grids with an increasing share of renewable energies.
Improved performance, better availability of spare parts and use of the latest technologies as well as analysis and monitoring tools – there are many arguments in favor of modernizing existing PV power plants. However, the complexity of such a project scares many system operators off, but a repowering project does not have to be labor-intensive. The SunnyDesign web portal provides an easy way to create a modernization plan for your own PV power plant in just a few clicks.
When Dennis Halpape and Alexander Krug journeyed to East Africa for the first time with Kassel-based association TOGETHER – Hilfe für Uganda [Aid for Uganda] to install a solar system twelve years ago, there was rarely any light to be found for many kilometers in every direction in the region of Kooki after sunset. Today, when it gets dark, there are significantly more lights on in the houses there.
Young people are key to the planet reaching its sustainability goals. So what could be better than installing solar panels on school rooftops? Schoolchildren can understand the technology involved; watch the installation of the equipment; and monitor the results. And, of course, the schools can reduce their carbon footprint.
The Serengeti National Park in Tanzania, Africa, is UNESCO World Heritage natural site and tourist magnet. Lions, leopards, elephants, rhinos and buffaloes still live in their natural habitat here. In order to preserve the natural environment, Tanganyika Expeditions has relied on photovoltaics for the operation of its accommodations and on e-mobility for the safaris.
SolarCoin migrates to the Energy Web Foundation: What you need to bear in mind following the migration of the SolarCoins
More than 17,000 PV systems in the Sunny Portal are benefiting from the advantages of a blockchain that is established...
With more than 450,000 downloads, the SMA Energy App is well established in the market. Now after more than one year of parallel operation, the SMA Energy App has replaced the Sunny Portal App. Reason for doing so: After all, PV systems are becoming ever more complex, and the integration of storage and e-mobility is set to become standard. The SMA Energy App combines your private energy transition at home with the change to e-vehicles on the street. We will improve our SMA Energy App following your feedback!
